Of what use is genius, if the organ is too convex or too concave and cannot find a
focal distance within the actual horizon of human life?
The main reflector parabolic generatrix has a
focal distance F = 2.917075[lambda] and axial tilt angle [gamma] = 102[degrees].
Mean values for UDVA, UNVA, CDVA, DCNVA, spherical equivalent, and optimal
focal distance for near vision are reported in Table 1.
Through the evaluation of the position ([X.sub.0], [Y.sub.0], and [Z.sub.0]) of the camera, taking pictures and its slope ([kappa], [psi], [omega]) with the applied collinearity condition will lead to the correlation between photo coordinate (x,y) and ground coordinate (X, Y, and Z) where C is the
focal distance.
With this work and those that followed, such as Water: Standard Version from the Cihai Dictionary, 1991;
Focal Distance, 1996; and Eating, 1997, Zhang used video to investigate the deep instability and intense incongruities of China in the final years of the century.
The major axis, minor axis, and the
focal distance of the elliptical cavity are A, B, and C in Figure 2, respectively.
The lenses also feature flange
focal distance adjustment and macro function, and are LDS (Lens Data System) and /i metadata-compatible.
To avoid the need of corrections, the transducer used in both measurements must be the same, and preferably a focused transducer, using therefore the
focal distance as the distance for the water surface and for the material surface.
The main feature of a lens is its
focal distance -- the point where far away light converges on passing through the lens.
They will then adjust the
focal distance of your prescription so it's precisely tuned for the distance of your front sights.
For example, because of the change of local temperature, atmospheric pressure, and
focal distance from the target, the aerial camera would easily become out of focus [1]; therefore, a robust system which can address this issue is crucial in aerial camera applications.
The goal was to find the largest step change that occurred precisely at the
focal distance, wherein the lens shaped the waves into plane wave.
focal distance - the distance from a lens to its focus
